Vertical Screw Conveyors

MLM shafted and shaftless Screw Conveyors are ideal for vertical conveying. As MLM fabricates our own spirals or shafted rotors, we can design the best solution to meet the requirements of your application. Vertical conveyors are an efficient process for elevating biosolids and the compact layout allows for the conveyor to fit in almost any plant layout.

Shafted Vertical Conveying

Operation - The high rpm of the balanced conveyor creates a centrifugal force which propels the product toward the outer casing. The closed casing ensures that the product is properly distributed across the circumference and the product is is spiralled to the discharge at the top.

Features:

• Large capacities at small sizes - larger capacities than are possible with a shaftless vertical conveyor - up to 160m3/hr or 5600ft3/hr!
• Enclosed and dust free
• Reliable operation

Shaftless Vertical Conveying

Operation - The vertical shaftless conveyor system is feed from a horizontal conveyor which creates a "plug" in the casing which then fills the tube allowing the spiral to lift the material to the top discharge. The lower rpm of the shaftless vertical systems are very efficient systems that offer the following features

• Larger capacities than shafted at similar sizes.
• Enclosed and dust free
• Reliable operation
• No centre tube to have stringy materials wrap around
• Low hp
• Long live
• No tail end bearing
